Acute pain is pain usually caused
by a recent injury or illness, be it physical or psychosomatic.
Typically, it helps to alert us when something is wrong. This
type of pain usually lasts a few days to months, until the
problem which first caused it is resolved. Chronic pain is pain
that persists or recurs for a prolonged period of time. This is
the type of pain which stems from ailments such as arthritis and
other joint problems, certain back conditions, injuries and
accidents, and many other problems concerning the nerves,
muscles, and bones but also including psychosomatic
disturbances. The experience of pain varies widely between
individuals, making its exact definition unclear to this day.
The treatment of pain, naturally,
was the first interest in electrotherapy and electromedical
research. For centuries electricity has been a challenge to
scientists. They have long known that it exists, and have
discovered how to generate it on a large scale, but found it
difficult to explain exactly what electricity is. That remains
even to this day in the orthodox, scientific fields. Around 600
BC, the Greeks found that by rubbing an 'electron' (a hard
Fossilized resin that today is known as Amber) against a fur
cloth, it would attract particles of straw. This strange effect
remained a mystery for over 2000 years, until, around AD 1600,
when Dr William Gilbert investigated the reactions of amber and
magnets and first recorded the word 'Electric' in a report on
the theory of magnetism. Gilbert's experiments led to a number
of investigations by many pioneers in the development of
electricity technology over the next 350 years.
The earliest references to the
use of electricity in medicine was the use of the Mediterranean
torpedo fish, a variety of electric ray. Aristotle and the
historian Pliny both referred to the effect of this fish.
Scironius Largus described it application for the treatment of
gout. Dioscorides, the famous physician who founded the Western
Materia Medica, Galen, and Paul of Aegina advised treatment by
electric shock from this fish for the treatment of headache.
In 1650, von Guericke built an
electrostatic machine containing a sulfur ball rubbed by hand.
The first recorded observation of the use of electricity
specifically for medical purposes in Europe was attributed to
Kratzenstein, professor of medicine at Halle . Jallabert,
professor of physics at Geneva , is said to have been the first
electrotherapist, for in 1747 he effected some improvement in a
locksmith’s arm that had been paralyzed for 15 years.
Jallabert
noted that when sparks were drawn from the arm, muscle
contractions were noted.
